Written by Dominique F. Weinstein (NARCAP International Technical Specialist and  France  GEIPAN/CNES expert), this 2012 report presents the findings of a comprehensive review of 600 cases, over a period of sixty-four years in which pilots have reported the presence of one or more unidentified aerial phenomena (UAP) during flight.

The main purpose of this report is to show that these phenomena occur, that they could have an impact on flight safety and that they deserve a more in-depth scientific study.
